To all whom z't may concern:

Be it known that I, EDWARD OToonn, a citizen of the United States, andresident of Gary, inthe county of McDowell and State of West Virginia,have invented certain new and useful Improvements in Car- DumpingApparatus, of which the following is a specication. 4

This invention relates to car dumping lo apparatus, and moreparticularly to car dumping apparatus for dumping mine cars, and has forits object the provision of such an apparatus that will be devoid ofmovable parts, and yet one that will invert the car and right it againwhile continuously moving along a track.

Another object is to provide a car dumping apparatus that will dump agreater number of cars than the dumping apparatus heretofore devised.

A further object is to provide a car dumping apparatus having the novelconstruction, design and combination of parts hereinafter described andillustrated in the accompanying drawings. v

In the drawings, Figure 1 is a somewhat diagrammatic plan of myinvention.

Figure 2 is a diagrammatic side elevation.

Figure 3 is a partial plan of the dumping track, and Figure 3 is acontinuation.

thereof.

Figure 4 is a partial side elevation of the entrance end of the dumpingtrack.

Figures 5, 6, 7 and 8 are transverse sectional elevations on the linesV-V, VI-VI, -VIl-VIL and VIH- VIII of Figure 3, showing' the differentpositions of the car when traveling along the dumping track. A

Figure 9 is a transverse sectional eleva tion through the dumping trackshowing a slightly modified arrangement.

Referring more particularly to the drawings, the letter A designates thesupply track leading to the dumping track B. C designates the locomotivereturn track and D the empt c`ar return track.

The supp y track A is of the usual track construction and consists ofties 2 and rails 3. The locomotive returny track C parallels the supplytrack and also -is of the usual track construction consisting of tiesflsupporting the rails 5. The locomotive return track C is connected tothe supply The car dumping track B forms a continuation of the supplytrack A and is inclined downwardly from the supply track sopas to causethe cars to travel along the same by gravity.

The track B comprises upper and lower rails 8 vand 9 mounted on yokes 10secured to beams 11, which bridge over a receivinf bin 12l belowthetrack. The rails 8 an 9 are disposed tread to tread, and spacedequidistant throughout their length to enable the wheels 14 of the cars15 to pass between them without binding. The track B is twisted to forma helical curve of 135 degrees in one direction to a point adjacent itstransverse center line, then continues straight for a short length, andthen is reverselytwisted in the opposite direction, forming a reversehelicalcurve of 135., degrees. It will thus be seen that cars passingalong the track B will iirst be inverted and then righted while incontinuous motion.

The track D or empty car return track B and is inclined `downwardly tothe point 16, at which point a cable hoist 17 is located toraise theempty cars u to normallevel where they may be moved y the locomotive toanypoint desired for reloading.

The rails 8 and 9 are provided with side llanges 18 and 19,respectively, to limitthe side movement of the cars during the dumpingoperation.

The operation of the apparatus above described will be readilyunderstood. The cars are moved by any welll known form of locomotive,cable or the like, along the supply track A. They then move by gravityalong the dumping track B where they are inverted and righted asheretofore described, and continue by gravity along the empty returntrack D to the point 16 where they are engaged by the cable hoist 17 andelevated to the normal level portion of the return track.

If a locomotive is used'to push the oars yforms a continuation of thedumping track l along the track A it will be switched at the switch 6 tothe ,locomotive return \track C. v

In Figure 9 an arrangement is shown for dumping cars having low \bodies,that is bodies lying close toy the wheels. In this construction thecarbody 15 pro'ects over the wheels 14 and is so close to t e wheelsthat it is not possible for the upper rails 8 to engage the' upperportion o the wheel tread. Therefore a bracket 22 is secured to eachside of the car vbody 15,\wh1ch brackets arevprovided with outwardlyexf` tending arms on which are journaled rollers 23, Aand the` rails 8are `spaced a greater distanceI apart than the rails' 9, lso as tooverlie the rollers 23 on vthe brackets 22 instead lof the wheels 14. V

In' operation the apparatus` of F igurewill function the samel as' thatbheretofore p described, with the exception that the rollers 23 willengage the rails 8 when the car y is being dumped, instead of the wheels14;

lWhile I' have shown and described only one specific embodiment of' myinvention 'y it will beunderstood that various modifications may be madewithout departing froml 'a two-rail dumping trackupon which all thewheels of the cars to be dumped are adapted to travel, ,a series ofretaining rails spaced above and .alined with the rails of said.Vdumping track, said dumping track comf prising a portion having both`rails twisted righting portion.

.up the carsas they uniformly in one direction from a horizontalposition through asuiiicient angle to dumpv cars passingalong saidtrack, and

'another`portion twisted uniformly in a reverse vrdirection ata point.beyond said `first mentioned twisted`portion to form a car 2. `A cardumping mechanism comprising asingle-track portion, means for slowingtrack, an inclined car umping track adapted to have thev cars movethereover by gravity, said dumping track comprising apair of tractionand .supporting rails and a pair of guard rails spaced above and inalinement with'said traction rails, said traction and said guard railsbeing' arranged tread to tread, and said dumping track having a portionof its length twisted helically in one Ydirection f and a second portiontwisted lieli cally in the reverse direction so as to autoass over saidsingle matically dump and right the cars passing thereover.`

3. A car dumping mechanism comprising a single supply track portion,means for slowing up the cars as they'pass over said singletrack, aninclined car dumping track adapted to have' the cars move thereover byravity,y said dumping track comprising a double track composed of a pairof traction and a pair of guard rails above said traction rails, saidtrac-tion rails and said guard rails being disposed tread to tread andhavino' a portion of their length twisted helica ly in one direction anda second portion twisted helically in the reverse direction so. as toautomatically dump and right the cars passing thereover, a return trackleading 'from said dumping rack havlng an upwardly inclined portion inits length, and

means for conve ing the cars along said upwardly incline track.

n 4. The combination Awith a section of helically'twistedtrack adaptedto invert and right cars passing thereover, of a supply trackcommunicating with the entrance end portion yof said returnAthereoffavlocomotive return track paralleling said supply track andconnected therewith by a switch, and an empty'car'return j trackcommunicating with the discharge end of said dumping track.

5. The combination with a section ofl helically twisted track adapted toinvert and right cars passing thereover, of a supplytrack communicatingwith the entrance end ythereof, a locomotive return track parallellbeinginclined-downwardly for a portion ofl its length and provided with a carelevating apparatus at the endof said inclined 6. The combination' witha section of inclined track twisted helically inopposite directions onthe opposite sides of its transverse 'center line, of a supplyl trackcommunicatng with thek entrance end thereof, a locomotive return trackparalleling said supply track and connected therewithrby a switch, vandan empty car return track communicating with the discharge end of saiddumping track, said empty car track being inclined downwardly for avportion` of its length and provided with a car elevating apparatus atthe end of said inclined`portion.

In testimony whereof I have hereunto set my hand.
